You really need to vibe qualify it, and make sure your ignition system (hot
surface or spark) is robust, and will not interfere with avionics. The
flyback style spart genarators create awful spikes that will just noise up
your voltage sensors, use current transducers.
Look into hot surface, but make sure it wont corrode. Design it so your
purge through (probably fuel purge after light) is enough mass flow to keep
it cool, and probably a good idea to have redundant ignition
surfaces/sparkers.

That looks remarkably like an XCOR runway static test crew back in the
day. It got pretty routine after a while.
Aside from the background blatantly not being Mojave. Switzerland looks a
lot nicer!

XCOR did 1000 consecutive igniter tests several times. It almost
became a rite of passage for interns.

Does anyone have data for what is the most number of ignitions
performed on bi-propellant, non-hypergolic rocket igniter
without being rebuilt? I know that XCOR has done thousands of
runs on their igniters, but I don't know how often they get
rebuilt or if anyone has performed comparable reliability tests.
What is the state of the art for igniter cycles?
Thanks,
